I want to enlist this project, but there only seems to be tars and not cvs/svn/git repository.
This is not the same as Apache_ssl.
Sorry, donert. An Ohloh report simply can't be generated without a revision history log.
We get a lot of requests to support tarball snapshots, and as time goes on and development resources become available we may come up with something here. Although we couldn't make very detailed reports, there are some usable metrics that could be derived.
Jason wrote a good post about this recently in the blog.
